IMPROVEMENT IN FASTENERS FOR MEETING-RAILS OF SASHES.

Specification forming part of Letters Patent No. 161,020, dated MarchQ3, 1,875; application led February 6, 1875.

To all whom tt may concern:

Be it known that I, EDWARD G. FELT- HoUsEN, of the city ot' Buffalo, inthe county of Erie and State of New York, have invented certainImprovements in Sash-Locks, of which the following` is a specification:

My invention relates to that kind of sashfastenings known asmeeting-rail sash-locks, which consist generally of an arm pivoted tothe upper side ofthe meeting-rail ot one sash, so as to swinghorizontally and project over the opposite rail of the other sash.

The object of my invention is to protect the locking-arm againstmovement by an instrument from the outside inserted between themeeting-rails for the purpose of unlocking the sash; and with thisobject in view, my invention consists of a gravity locking-catch,adapted to drop over the locking-arm, and provided with a suitableshoulder to prevent the arm from being returned, as will be hereinaftermore fully set forth.

In the accompanying drawings, Figure l is a plan View of asash-fasteningprovided with my improvements. Fig.'2 is afront elevation, and Fig. 3 aside elevation, thereof.

Like letters of reference designate like parts in cach ofthe figures.

. A represents the lockingarm ot' the fastening, pivoted to abearing-plate, B, secured by screws to the top ofthe meeting-rail of theupper sash, in a common manner. C is a plate secured to the oppositemeeting-rail, and provided With a curved ledge, o, with which a notch,a, on the under side of the locking-arm engages as it is swung around,for the purpose of drawing the sash together to prevent rattling of thesame, which is, however, an old feature of construction. D is my gravitylocking-catch, pivoted to au upwardly-projecting lug, e, cast with theplate O. The catch D is provided with a jog or lockingshoulder, d, andits end or face is beveled on the under side, so as to cause thelocking-arm, as it is swung around, to strike against this incline andswing upward the catch, until the arm has reached its locking positionand passed the shoulder d, when the catch descends to its formerposition and locks the arm, as clearly shown in Fig. 2.

As represented in the drawing, the upper side of the arm A, at the pointWhere it engages with the catch D, is recessed and beveled off, so as tofacilitate its engagement with the catch and render the device morecompact. The lug e, which forms the bearing ot' the catch D, also servesas a stop to arrest the movement ot' the arm A, when it has arrived atits proper locking position. The lockingarm is readily released byraising the catch D with one n ger, when thearm can be readily swungaround from disengagement with the meeting-rail in the common manner.

Vhat I claim as my invention is- The combination, with the pivoted armA, of the gravity locking-catch D, pivoted to lug` e, and provided witha suitable shoulder, d, substantially as and for the purposeshereinbefore set forth.
